4 Claims.

This invention relates to printing presses, and more particularlypresses of rotary character; and it is among the objects of theinvention to provide equipment for high speed throughput of web feed andcut-sheet flat delivery. Other objects and advantages will appear as thedescription proceeds.

To the accomplishment of the foregoing and related ends, the invention,then, comprises the features hereinafter fully described, andparticularly pointed out in the claims, the following description andthe annexed drawings setting forth in detail an illustrative embodimentof .the invention, this being indicative however, of but one of thevarious ways in which the principle of the invention may be employed.

In said annexed drawingsz- Y Fig. 1 is a side elevational view ofsanembodiment of the invention, parts being broken away; Fig. 2 is a planview of the assembler portion thereof; and Fig. 3 is a vertical sectiontakenon a plane substantially indicated by line III-III, Fig. 2.

Referring more particularly to the drawings,

. there is shown rotary printing press means comprising cylinders 2, 3,4, 5, operating upon a web 'w of paper, printing the same on both sides,the construction of the printing press being along 'known lines, andpreferably of perfecting newspaper press character, and requiring nofurther particularly detailed showing. As many webs w, w' as desired,each similarly coming from such printing cylinders, are brought togetherby the guide rolls 6, 7, in the end frame 8. Adjacent the latter is aframe 9 within which is mounted a revolving knife 10, carried by a shaft11 which is geared in step with the press rolls, through theintermediary of gearing 12, 13, 14, sprocket chain 15, shaft 16, bevelgearing 17, and shaft 18 which is coupled to the printing press drive.Mounted adjustably on a block 20 on the frame 9 is a stationary blade 21which coacts with the revolving blade 10. Above the knife 2l is a guideplate 22 and guide rolls 23, 24, the latter being surfaced to maintainthe paper smooth, as for instance by divergent ribs 25.

Below the stationary knife blade 21 is an apron guide 26, and a slopingconveyor belt 27 in the form of narrow strands or tapes; andinterdigitating therewith is another conveyor 28 almost horizontallypositioned between rollers 29, 30. Beyond the latter belt and at aslightly lower level is a further conveyor 31 between rollers 32 and 33.Upper conveyor tapes 34 are positioned above, in relation to formguides. The conveyor 2'7 is driven by sprocket chain 35, running overits roller 36, on a shaft in common with the sprocket receiving thechain. Conveyor 28 is similarly driven by drive belt 35 running underthe sprocket 29 on its roller shaft. Conveyor 3l is driven by a drivebelt 37 which takes over a cone pulley 38 for adjustment of speed. Drivebelt 35 is also engaged overacone pulley 39, for speed adjustment. Theframe 4) carrying the conveyor 31, etc. and fitting within the standardsof the frame 9, also carries a pair of racks 41 upon which are mountedguide rolls or trolleys 42, for maintaining the sheets in smoothcondition in transitf At the end of the frame is a discharge roller orrollers 43, which engage the sheets and throw them in turn upon thedelivery table 44, in suitable jogging guides at the ends and sidesthereof (which may be of known detail and require no further showing).The delivery table 44 is lowered in proportion with the increasingstack,

by lowering means 45, which may also be of known' detail, and requiresno further showing.

Webs of paper w, w etc. proceeding between the printing cylinders areprinted on both sides and brought together between the guide rolls 6 and7, and passed thence through the guide rolls 23, 24, and over theinclined plate 22 to the cutter 10, 21. The cut sheets feed down thenceonto the conveyor 27,"and then to the conveyor 28, from which they areforwarded to conveyor 3l. By setting the cone drive 38, 39,appropriately, the speed of conveyor 31 may be adjusted to 10-80 percent that of the web feed further back, and the sheets are therebycaused to correspondingly overlap in accumulatinvention may be employed,change being made as regards the details described, provided the meansstated in any of the following claims, or the equivalent of such, beemployed.

I therefore particularly point out and distinctly A claim as myinvention:-

1. Delivery means for receiving sheets from printing and cuttingmachines, which comprises an inclined conveyor receiving the out sheets,a further conveyor, a frame supporting said conveyor, overheadguide-rolls above said last# 3. Delivery means for receiving sheets fromprinting and cutting machines, which comprises an inclined conveyorextending below the cutter of such cutting machine, a substantiallyhorizontal conveyor adjacent said first-named conveyor,

another conveyor beyond and below said lastnamed conveyor, a framecarrying said last conveyor, guide rolls above said last-mentionedconveyor, rack and pinion means in said last frame for adjusting saidguide rolls, a receiving table, and discharge rolls in the end of saidframe for discharging the sheets onto said table.

4. Delivery means for receiving sheets from printing and cuttingmachines, comprising Va frame independent of but fitting within theframe of such cutting machine, a conveyor in said frame for receivingthe cut sheets, a further conveyor receiving the sheets from saidiirstmentoned conveyor, and overhead guide means above said lastconveyor regulable/longitudinally with relation thereto.
